Several Platform as a Service (PaaS) options exist for hosting a web app. Heroku and Amazon Web Services are the most common, but they have a steep learning curve.
Best solution: Heroku
Heroku makes deployment of arbitrary apps including Panel apps and dashboards very easy and provides a free tier to get you started.
- First, signup for a Heroku free account
- Download and install the command line interface (CLI).
- See the "Heroku Example" for Dash: https://dash.plot.ly/deployment
Recommended Workflow: design and test locally and then once everything is working, follow the above steps to upload your code to PythonAnywhere.
There are two options for deploying Panel apps: Binder & Heroku.
- the example Panel apps provide options to launch the apps from the GitHub repositories on Binder
- a free service!
- a reasonable amount of free storage provided, e.g., enough to host the dataset of 1 million taxi trips
To generate custom links for your Binder apps that say launch app and launch notebook using
this page: https://mybinder.readthedocs.io/en/latest/howto/badges.html.
You can create the link for your app from the Binder homepage: https://mybinder.org/
You'll want to create two links:
- Enter your repository URL
- Specify the file path as
app.ipynb(or whatever you app notebook is called!)
- Enter your repository URL
- Specify the URL path as
/panel/app
Note: if you named your file name app-name.ipynb, you should instead use: /panel/app-name
Panel apps can be deployed to Heroku, but Heroku's doesn't do file storage, e.g., you can't host any data files locally to be loaded by your app, which makes things overly complicated. If file storage isn't a concern, then Heroku can provide a good fit for deployment.
The Philadelphia shootings app has been deployed to Heroku and includes instructions on how to do so.
